Hi all,
I''m having a hell of a time getting my IFB to work. I know I''ve done
this before, so I''m missing something stupid. Can anybody tell me what
it might be?
Configs as follows:
--------
#!/bin/sh
modprobe ifb numifbs=1000
modprobe act_mirred
modprobe 8021q
brctl addbr br0
brctl setfd br0 0
brctl stp br0 off
brctl addif br0 eth1
brctl addif br0 eth2
ifconfig eth1

multiple IFBs
Hi all,
Further to my previous questions, I need lots of IFBs on this thing.
I have configured IFB as a module, and issuing a modprobe ifb loads it,
but only gives me 2 IFBs (ifb0 and ifb1). How can I get more? I''m
probably looking at needing about 20 on this project.
Regards,
Leigh

Adding qdiscs crashes kernel??
Hi all,
I''m having some problems setting up qdiscs on a bridge.The config looks
a little like this:
ifconfig ifb0 up # Bring up the IFB for this bridge.
tc qdisc add dev eth2 ingress
tc qdisc add dev eth3 ingress
tc qdisc add dev ifb0 root handle 1:0 cbq bandwidth 100Mbit avpkt 1000
cell 8
# Raw qdiscs on each bridge port
tc qdisc add dev eth2 root handle 1:0 cbq bandwidth

TC not recognising "mirred" argument
Hi All,
I''m trying to do some traffic shaping with IFB. I have installed Ubuntu
6.0.6 and upgraded to the 2.6.17.7 kernel. I have an ifb0 device.
However, I think I may have the wrong version of TC installed, because
it doesn''t like the ''mirred'' argument.
What version of iproute should I be using, and how can I upgrade it?
apt-get update iproute

Setting max latency on classful qdiscs
Hi All,
I''m using HTB to shape traffic, a little like this:

Rate limits whithin rate limits
Hi all,
I''m sure I''m soing something wrong here.
I am trying to set up a rate limit inside another rate limit.
eg. I have a 512K rate limit on a particular VLAN. I am using an IFB so
that packets passing through the bridge are counted at each port.(ie the
throughput is limited to 512K, not just the traffic in one direction.)
This part works OK, but I also want to limit a

invoking ebtables with tc
Hi all,
Is it possible to invoke an ebtables target from tc?
Ie we can use the ''action ipt'' to invoke an IPTables target, but I was
wanting to use an ebtables target instead. Is this possible?

rp_filter and fib_validate_source sequence in KPTD
Hello all,
My question:
- - - - - - -
Does anybody know when the reverse path filtering occurs as the packet
traverses the kernel?
Does it happen before NF_IP_PRE_ROUTING (PREROUTING) or not?
Does it only happen at route selection time?
What I have tried to do to find the answer:

Cbq and max latency
Hi All,
Is there any way to set the maximum latency on a cbq when it is
overloaded?
Or, for that matter, to query it?
For example, I want to know how long (in seconds) a packet will stay in
the queue before it is dropped, and I want to be able to adjust this
figure.

Leigh

U32 VLAN Header match
Hi all,
Is is possible to configure the u32 classifier to match on VLAN ID? Or
any other bits in the 802.1 header for that matter?
If so, can anybody tell me how? Or where to find out how?

changing 802.1p priority
Hi All,
Is it possible to mangle the 802.1p priority bit on a packet as it gets
bridged? I can''t find anything in either the iptables or ebtables docs
to tell me how it''s done.

Some advanced filtering questions
Hi All,
I need to do some tricky filtering stuff. Can anyone tell me if any of
the following are possible?
* match on a combination of firewall mark AND u32 criteria. ie. handle
6 fw AND u32 match ip src 1.2.3.4/32 - to match packets from 1.2.3.4
which have been marked elsewhere
OR
* to OR the values of u32 matches. Something like u32 match ip src
1.2.3.4/32 OR match ip dst 1.2.3.4/32 - to

Applying the same class to multiple interfaces
Hi All,
I''m trying to do some traffic shaping on an ethernet bridge. Currently,
I have the following setup working:
ifconfig eth0 down
brctl addbr br0
brctl addif br0 eth0
brctl addif br0 eth1
brctl stp br0 off
ifconfig eth0 0.0.0.0 up
ifconfig eth1 0.0.0.0 up
ifconfig br0 up
This creates a bridge consisting of eth0 and eth1. So far so good.
I now want to use tc to shape traffic

dev IFB, few questions
I''ve made some tests...
eth2 is my internal interface, LAN is connected here.
Before I had IMQ device in AB mode...
PREROUTING [A]fter NAT, POSTROUTING [B]efore NAT.
I want the same situation on ifb.
I do this in this way:
---
# incoming traffic here from LAN is before NAT
tc qdisc add dev eth2 handle ffff: ingress
# outcoming traffic here from WAN is after NAT
tc qdisc add dev eth2

IFB & 802.1q
Hello
What I''m looking for is how to configure the Linux QoS module to do
global rate limitation for two (or more) 802.1q pseudo network devices.
I naturally suppose there is a possibility with IFB. I don''t want to use
IMQ because it''s not integrated to my kernel v2.6.21.1 and I didn''t find
IMQ patches for it nor for the iptables package I use (v1.3.7).

Shorewall & IFB
Hello Tom!
After i read and analyze some docs about IFB i decide that for implement
this feature in Shorewall not need more efforts (of course i may be wrong).
If we have 'ifb0' device then we must activate ingress discipline on real
device (f.e. eth2) and redirect 'egress' from it to 'ifb0'.
tc qdisc add dev eth2 ingress
tc filter add dev eth2 parent ffff: protocol ip
